Subject: [PATCH 4.9 01/36] openrisc: Fix a memory leak
Date: Mon, 24 May 2021 17:24:46 +0200	[thread overview]
Message-ID: <20210524152324.210894968@linuxfoundation.org> (raw)
In-Reply-To: <20210524152324.158146731@linuxfoundation.org>

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit c019d92457826bb7b2091c86f36adb5de08405f9 ]

'setup_find_cpu_node()' take a reference on the node it returns.
This reference must be decremented when not needed anymore, or there will
be a leak.

Add the missing 'of_node_put(cpu)'.

Note that 'setup_cpuinfo()' that also calls this function already has a
correct 'of_node_put(cpu)' at its end.

Fixes: 9d02a4283e9c ("OpenRISC: Boot code")
